I'm the head developer for Zoombies, the DayZ port to ArmA 3.
We use All in ArmA to be able to utilize the old models, textures, and maps. We do have a slight problem though:
On random occasions, the whole server, along with all the clients connected to it, will crash (Arma 3.exe has stopped working). I've talked to kju from AiA's devheaven and he told me to report it here. He told me that crashes can happen when killing someone with a gun without a geometry LOD. I do not understand what that means because I have no experience with editing or creating models for ArmA. I have not edited any models for guns. I have only added 1 custom ArmA 2 unit, but we have seen many crashes occur when killing snipers in gillie suits along with PMC Civs (Survivor). {F21164} {F21165}
